Control charts are extensively used in manufacturing contexts to monitor production processes. This article illustrates economical design of a variable sample size and control limit Hotelling’s T2 control chart based on a novel cost model when occurrence times of the assignable causes are exponentially distributed. The proposed nonlinear cost model is an extension of Duncan’s (J Am Stat ...

objective: diabetes is a chronic disease that causes severe side effects in patients. according to the previous studies, the incidence of depression and anxiety is higher among patients with diabetes type 2. the present study was conducted with the aim of examining the effectiveness of mindfulness-based stress reduction program and conscious yoga on depression, anxiety and stress in patients wi...

Multivariate functional anomaly detection has received a large amount of attention recently. Accounting both the time dimension and correlations between variables is challenging due to existence different types outliers data. In context predictive maintenance quality control, data sets often contain number variables. However, most existing methods focus on small Moreover, in fields that have hi...

Despite many technological and computational advances, the results of a mass spectrometry proteomics experiment are still subject to a large variability. For the understanding and evaluation of how technical variability affects the results of an experiment, several computationally derived quality control metrics have been introduced. However, despite the availability of these metrics, a systema...

Multivariate control chats are generally used in situations where the simultaneous monitoring or control of two or more related quality characteristics is necessary. In most processes in the real world, distribution of the process characteristics are unknown or at least non-normal, so the non-parametric or distribution-free charts are desirable. Most non-parametric statistical process-control t...

objectives:  this  study  aimed  to  examine  the  effectiveness  of  life  skills  training  on  quality  of  life  in mothers of children with down syndrome.  methods:  this  research  was  done  as  a  semi-experimental  with  pre-post  test  and  with  control  group. statistical population included all children with down syndrome, age from 2 months to 8 years, and their mothers who referre...

Woodall and Montgomery [35] in a discussion paper, state that multivariate process control is one of the most rapidly developing sections of statistical process control. Nowadays, in industry, there are many situations in which the simultaneous monitoring or control, of two or more related quality process characteristics is necessary. Process monitoring problems in which several related variabl...

Multivariate Process Capability Indices (MPCI) show how well a manufacturing process can meet specifica-tion limits when quality characteristics enclose a relative correlation. Process capability is an important and commonly used metric for assessing and improving the quality of a production process. When quality charac-teristics of a product are correlated then an attractive comes close to MPC...

background: bipolar mood disorder (bmd) is a type of mood disorder which is associated with various disabilities. the family members of the patients with bmd experience many difficulties and pressures during the periods of treatment, rehabilitation and recovery and their quality of life (qol) is threatened. in the present study, we aimed to evaluate the effect of family-centered education on me...
